Product Description
Air quality monitor uses a built-in large-screen LCD display, which can monitor 11 indoor air indicators. The measured data can be uploaded to the free data platform through RS485, WIFI, or Ethernet, so that users can view it in real-time. This air quality monitor is widely used in building HVAC, building energy saving, smart homes, schools, airport stations, and other places.
Product Features
The air quality detector is a product that can detect formaldehyde, PM2.5, TVOC, illuminance, noise, temperature and humidity and other gases in real-time. Small size, easy to move. Through its internal sensor, it can accurately measure the concentration of various pollutants. Alarm when the concentration exceeds the standard.
Air quality monitor working principle: The signal measured by the sensor is amplified by the operational amplifier, and the noise interference is removed by the filter circuit. Then through AD acquisition and 32-bit high-precision CPU processing and calculation, it is converted into a pollutant concentration value and displayed on the LCD screen.
